+# Phase 1 Plan 02: Core Models, Messages, and Infrastructure Helpers Summary
+
+**7 Core/Infrastructure files providing typed contracts (TenantProfile, OperationProgress, messages, CSOM pagination helper, throttle-aware retry helper, RichTextBox Serilog sink) — 0 errors, 0 warnings**
+
+## Performance
+
+- **Duration:** 1 min
+- **Started:** 2026-04-02T10:04:59Z
+- **Completed:** 2026-04-02T10:06:00Z
+- **Tasks:** 2
+- **Files modified:** 7
+
+## Accomplishments
+
+- All 7 Core/Infrastructure files created and compiling with 0 errors, 0 warnings
+- TenantProfile fields match JSON schema exactly (Name/TenantUrl/ClientId)
+- OperationProgress record with Indeterminate factory, usable by all feature services via IProgress<T>
+- TenantSwitchedMessage and LanguageChangedMessage correctly inherit ValueChangedMessage<T> for WeakReferenceMessenger broadcast
+- SharePointPaginationHelper iterates past 5,000 items using ListItemCollectionPosition do/while loop; RowLimit=2000
+- ExecuteQueryRetryHelper surfaces retry events via IProgress<OperationProgress> with exponential backoff (10s, 20s, 40s, 80s, 160s)
+- LogPanelSink writes color-coded, timestamped entries to RichTextBox via Dispatcher.InvokeAsync for thread safety
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Core models and WeakReferenceMessenger messages** - `ddb216b` (feat)
+2. **Task 2: SharePointPaginationHelper, ExecuteQueryRetryHelper, LogPanelSink** - `c297801` (feat)
+
+**Plan metadata:** (docs commit follows)
+
+## Files Created/Modified
+
+- `SharepointToolbox/Core/Models/TenantProfile.cs` - Plain class; Name/TenantUrl/ClientId match JSON schema
+- `SharepointToolbox/Core/Models/OperationProgress.cs` - Record with Indeterminate factory; IProgress<T> contract
+- `SharepointToolbox/Core/Messages/TenantSwitchedMessage.cs` - ValueChangedMessage<TenantProfile>; WeakReferenceMessenger broadcast
+- `SharepointToolbox/Core/Messages/LanguageChangedMessage.cs` - ValueChangedMessage<string>; WeakReferenceMessenger broadcast
+- `SharepointToolbox/Core/Helpers/SharePointPaginationHelper.cs` - Async iterator; ListItemCollectionPosition loop; [EnumeratorCancellation]
+- `SharepointToolbox/Core/Helpers/ExecuteQueryRetryHelper.cs` - Retry on 429/503/throttle; exponential backoff; IProgress surfacing
+- `SharepointToolbox/Infrastructure/Logging/LogPanelSink.cs` - ILogEventSink; Dispatcher.InvokeAsync; color-coded by level
+
+## Decisions Made
+
+- TenantProfile is a plain mutable class (not a record) — System.Text.Json deserialization requires a parameterless constructor and settable properties; field names match the existing JSON schema exactly to avoid serialization mismatches.
+- SharePointPaginationHelper.GetAllItemsAsync decorates `ct` with `[EnumeratorCancellation]` — without this attribute, cancellation tokens passed via `WithCancellation()` on the async enumerable are silently ignored. This is a correctness requirement for callers who use the cancellation pattern.
+- ExecuteQueryRetryHelper.IsThrottleException checks for "429", "503", and "throttl" (case-insensitive) — PnP.Framework surfaces HTTP errors in the exception message rather than a dedicated exception type; this covers all known throttle surfaces.
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 2 - Missing critical functionality] Added [EnumeratorCancellation] attribute to SharePointPaginationHelper**
+- **Found during:** Task 2 (dotnet build)
+- **Issue:** CS8425 warning — async iterator with `CancellationToken ct` parameter missing `[EnumeratorCancellation]`; without it, cancellation via `WithCancellation(ct)` on the `IAsyncEnumerable<T>` is silently dropped, breaking cancellation for all callers
+- **Fix:** Added `using System.Runtime.CompilerServices;` and `[EnumeratorCancellation]` attribute on the `ct` parameter
+- **Files modified:** `SharepointToolbox/Core/Helpers/SharePointPaginationHelper.cs`
+- **Verification:** Build 0 warnings, 0 errors after fix
+- **Committed in:** c297801 (Task 2 commit)
+
+---
+
+**Total deviations:** 1 auto-fixed (Rule 2 — missing critical functionality for correct cancellation behavior)
+**Impact on plan:** Fix required for correct operation. One line change, no scope creep.
+
+## Issues Encountered
+
+None beyond the auto-fixed deviation above.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All contracts in place for plan 01-03 (ProfileService uses TenantProfile)
+- All contracts in place for plan 01-04 (MsalClientFactory uses TenantProfile.ClientId/TenantUrl)
+- All contracts in place for plan 01-05 (LoggingIntegration uses LogPanelSink; LanguageChangedMessage for TranslationSource)
+- All contracts in place for plan 01-06 (FeatureViewModelBase uses OperationProgress + IProgress<T>)
+- All Phase 2+ SharePoint feature services can use pagination and retry helpers immediately
